IMPROVEMENT IN LOG-TURNERS.

Specification forming part of Letters Patent No. 14!,736, dated August12, 1873; application filed May 10, 1873.

To all whom it may concern:

Be it known that I, ESAU TARRANT, of Muskegon, in the county of Muskegonand State of Michigan, have invented a new and useful Improvement inLog-Turners for Saw- Mills, of which the following is a specification:

Figure 1 is a top view of my improved machine. Fig. 2 is a side view ofthe same, part being broken away to show the construction.

Similar letters of reference indicate corresponding parts.

The invention consists in the improvement of log rolling machines, ashereinafter described and claimed.

A represents the log-deck, the forward part of which is made inclined,as shown in Fig. 2, so that when a log is rolled past its center it mayroll directly upon the carriage B, where it is stopped in properposition by the standards O in the head-block. D isa wheel, or segmentof a wheel, the axle of which works in short guide slots in the middlepart of the log-deck A.

I prefer to make the wheel D in the form of a half-wheel or semicircle,and to arrange its axle E in such a position that the straight side ofthe said wheel or segment, when turned into the horizontal position, maybe a little below the top line of the log-deck A, so as to be out of theway of the logs when rolled upon said deck.

One side of the convex face or rim of the wheel D is rabbeted, and inthis rabbet are formed teeth I the heads of which are a little withinthe circle of the rim of said wheel. The teeth F mesh into the teeth ofthe small gear-wheel G attached to the shaft or axle H, which works inbearings attached to some suitable support, and to which power may beapplied from the driving mechanism of the mill by friction or otherconvenient means. I are bars, in the lower ends of which the shaft H,and in the upper ends of which the shaft E, revolve.

The shafts E H work loosely in the standards I, so that the wheel D,while being securely supported, may vibrate should the log be crooked ornot round.

To the face of the forward part of the wheel or segment D may beattached spikes or points J, to take hold of the log and roll or turn itwhen upon the carriage B.

By this construction, when the gear; wheel G is turned in one directionthe rear part of the segment D will rise, as shown in .Fig. 2, rollingthe log past its center, when the inclination of the forward part of thelog deck A will cause it to roll upon the carriage B, where it will bestopped by the standards 0. By turning the gear-wheel D in the otherdirection its forward part will rise, the spikes or points J taking holdof the log and turning it into any desired position, as also shown inFig. 2.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The segment D, cog-toothed at F, and supported in the side pieces ofthe logdeck A, in combination with the said logdeck and the pinion Gr,as and for the purpose specified.

2. The segment D, cog-toothed and spiked at F J, respectively, andjournaled in the up: per ends of bars I, with the outer ends of the axleof the segment resting in curved slots in the side piecesof thelog-deck, in combination with said slots, the log-deck A, the bars I,and pinion G, as and for the purpose specified.
